Unformatted text preview: nvulsions Objective 3: Objective Describe the role of the kidney in correcting acid-base imbalances. What two systems are involved in acid-base balance? Bicarbonate Buffer System Respiratory Component CO2 + H2O Renal Component H2CO3 H+ + HCO3- + Na+ Cl- or HCO3- K+ or H+ To Correct an Alkalosis To • Respiratory system – decreases respiratory rate, retaining CO2. The carbonic acid produced dissociates into H+ (which helps neutralize excess OH-) and excess (unneeded) bicarbonate ion. • Kidney – Helps eliminate excess bicarbonate ion by reabsorbing less bicarbonate and more chloride. – Helps retain needed H+ by secreting less H+ and more K+. To Correct an Ac...
